Ultraspire UltraFlask Colour:Blue We eat a “balanced” dietUltrAspire introduces yet another milestone in hydration history! The Ultraflask 550 Hybrid Bottle has all the benefits of a softflask but with the conveniences of a hard bottle. The bottle is designed to sit as close to the body as possible to minimize movement when full. The soft body shape helps with rapid access, comfort, and squeeze. The large cap opening easily fits ice cubes and is covered by a high flow push pull valve. Made in the USA.
